"No it won’t, as the two viruses are very different," says Dr. Kuldeep Kumar Grover, Head of critical care & Pulmonology - CK Birla Hospital, Gurgaon.

“Since the virus causing COVID infection is completely different from that inflicted with H3N2, the vaccines will be different and the COVID vaccine will not help in protecting against influenza. There are other vaccines, flu shots and influenza vaccines available which helps in preparing the immune system for the fight against the particular disease/ virus,” the expert explains.

“Vaccine against any virus is made depending on the nature of the virus, its morphology, proliferation rate etc, thus it is important to understand that the particular vaccines will only trigger the immune system to respond correspondingly to the virus,” he adds.
